Months to Pay Off vs Fixed Monthly Payment
公式
Debt Payoff Timeline
A payoff timeline shows how each payment is split between interest and principal.
Early vs Late Payments
In the early months, a large portion goes to interest. As the balance shrinks, more of each payment attacks the principal. This is why extra payments early on are so powerful.
Month 1 Breakdown
This process repeats each month until the balance reaches zero.
计算示例
$20,000 at 15% with $600/month payments.
- 01Month 1 interest = $20,000 x 1.25% = $250
- 02Month 1 principal = $600 - $250 = $350
- 03New balance = $20,000 - $350 = $19,650
- 04Total payoff = 42 months (3.5 years)
- 05Total interest = $5,200
常见问题
Why does so much go to interest at first?
Interest is calculated on the remaining balance. When the balance is high, the interest charge is high, leaving less for principal reduction. As the balance falls, the interest portion decreases and more goes to principal.
How do extra payments affect the timeline?
Extra payments go directly to principal, which reduces the balance faster and thus reduces future interest charges. This creates a compound effect -- every extra dollar paid early saves more than one paid later.
Is a shorter payoff always better?
Shorter payoff saves the most money but requires higher monthly payments. Balance the desire to be debt-free with maintaining enough cash flow for emergencies and other financial goals.
